HYDRANT.

SPECIFICATION forming part of Letters Patent No. 444,329, dated January 6, 1891. Application filed August Il., 1890. Serial No. 361,738. (No model.)

To @ZZ whom z' may concern:

Be it known that I, THOMAS W. BROOKS, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in lVater- Hydrants; and I declare the following to be a true and exact description of the same, reference being had to the accompanying drawings.

The object of my invention is to provide in the most simple manner means of opening and closing street-hydrants, permitting a free flow of the Water, and also in providing a jointedcrane of metal constructed as an integral part of the hydrant, with a swivel movement by means of metallic joints.

Figure l is an elevation, partly in section, of one of my improved hydrants, including a Water-crane for supplying carts attached or in position. Fig. 2 is an elevation of one of my improved hydrants with the water-crane omitted. Fig. 3 is a transverse section on line z z of Fig. 2, showing the construction of the screw-nut and nozzles.

Referring to the drawings, the main barrel A is made of cast-iron in the usual manner, with a strong covering-plate B and supplelnentary cover C. To the base is bolted the foot piece or chamber D to receive the inletpipe E and the valve-seat F. The valve G is composed of a strong metallic core-piece II, an annular ring of flexible material I, and a follower-nut J, held by a screw-thread on the end of the valve-stem K. The valve-seat F is made of non-corrosive metal and clamped between the foot-piece D and the main barrel A, as shown in Fig. l.

To open and close the valve G, I employ a screw-stem L with a squared extension IWI to receive a key outside the cover C. On the top of the `main valve-stem K is attached a long nut N, which nut slides up and down in the sleeve or guide O, attached to and formed integrally with the main cover B. To prevent the nut N from turning in sleeve O, it is made with lugs l? P, moving in slots formed in O, as shown in Fig. 3. The screw-stem L has a collar at Q, on which rests fibrous packing compressed by the gland R, preventing end movement, as shown.

At S S are provided one or more outlet-nipples for connecting hose and provided with screw-covers in the usual manner.

Vhen required, I attach to my improved.

hydrants a Water-crane composed of vertical and horizontal sections U U2. The vertical stem of the crane-stem U is flanged and bolted to the extension T, as indicated in Fig. l. This extension T is arranged flush with the top of the ground, and when the crane U is not required a cover B2 is substituted. At the top of the stem U is a swivel-joint cornposed of the two members IV and X and a packing-gland Y, so arranged that the horizontal section of the crane U2 can swing throughout a complete circle. The sleeve X is held firmly on its seat Z by the screw-'bolt V2, passing through its axis and into a nut N2, formed solid with the section U. At the outer of U2 is a valve G2, which is opened or closed as the crane or t-he nozzles S may be in use.

I am aware that screW-valves operated from the outside are common in the combination of hydrants, also that elevated pipes are attached to hydrants for filling water-carts, and I do not claim such apparatus; but

What I do claim, and desire to secure by Letters Patent, iss- 1. In a hydrant, the combination of the main barrel A, having the covering-plate B and supplementary cover C, the foot-chamber D, receiving the valve-seat F and the inlet-pipe E, the valve G, having the metallic core H, the annular ring` of flexible material I, and the follower-nut J, the valve-stem K, the screw-stem L, having the squared eXtension M, the long nut N, connected to the top end of the valve-stem K and sliding up and down in the sleeve or guide O, formed integral with the cover B, said nut N being provided with lugs P I), which 'move in slides formed in the guide O, substantially as de` scribed. Y 2. In a Waterhydrant, the main barrel A, formed with an extension T, a vertical pipe U, bolted thereon, and a swivel-joint at the top, held by a central screw-bolt V2, the whole combined and operating substantially in the manner and for the purposes specified.
